Can the amplifier be fixed or must be replaiced? on 2006 Mercedes-Benz ML350 4MATIC

Do you think - in case the amplifier is broken - that it can be fixed, or it must always be replaced? I have checked the price of that and it is not a low priced item.

Have you checked for a blown fuse? May be located at the amp.
